[Message part 1 (text/plain, inline)]

emacs 26.3. 2 different builds. 2 distinct OSs.

One build is custom inside Slackware; another build is standard issue from
Fedora 32.

Results below are identical for both situations.

If the tex / latex source (or a symbolic link) resides in /tmp directory,
everything from the tex mode menu functions as expected.

If the source is anywhere else in the directory structure, the first step,
compilation (tex / latex), fails because it can *not* find the source file.
Yet, if I use my own custom elisp script or invoke the relevant commands
manually, there is *no* problem.

The builtin tex-mode.el script seems to expect all code to be only in /tmp
or nothing will occur.

Am I missing something? A variable setting? Some other configuration aspect?

Thanks for your attention.

Guido

Invoking
    emacs  /path/to/file.tex
followed by C-c C-f does work.

But doing
    emacs  /path/to
then opening file.tex from dired followed by C-c C-f does not work.

Apparently tex-mode.el is *not *sending the correct full path to pdftex; it
does *not* find the input file under many circumstances.

I'm unable to reproduce this in Emacs 26.3.

Here's my test case:

emacs -nw ~/src/emacs/trunk/etc/refcards/refcard.tex
`C-c C-f' -> a dvi file is made

emacs -nw ~/src/emacs/trunk/etc/refcards/
open refcard.tex
`C-c C-f' -> a dvi file is made

Are you able to reproduce this if you start emacs with -Q?

I have tried the tests you suggest on refcard.tex (plus a few others in
that dir) with & without -Q cl switch; nearly all failed to produce a dvi.
Immediately tex fails since it can *not* find the source file as I
described previously. (Also review additional material in bug 42624.) The
results are identical on both a Slackware-current partition installation &
on a Fedora 32 partition installation.

The Texlive installations are current & direct compilation on any tex /
latex source files functions flawlessly. I also have a tiny piece of lisp
code that directly invokes, via start-process, the tex / latex compiler;
it, too, never has a problem.

Reiterating, the tex-shell created by tex-mode.el does *not* see a path to
the source unless modifications I suggest are made as in bug 42624.

Is this possibly a configuration issue? Could there be hidden environmental
variables that need to be set either in my bash shell or something I am
missing in the init.el? Official emacs documentation about tex-mode says
little about this matter. As an aside, inside tex-mode.el, there is a
getenv ESHELL command. Does ESHELL need some special attention?

I don't know -- I've tried your recipe for the bug on two different
(Debian and Ubuntu) machines, and I'm unable to reproduce it with "emacs
-Q" on Emacs 26.3.

So I think it sounds like a configuration issue on your side somewhere,
but I haven't used tex otherwise in quite a few years.

A test using a Fedora 32 Live image + emacs + texlive-collection-latex
could not replicate the build failure described on this reporter's machine.
The latter has some problem with configuration or missing packages. As
such, these postings should be removed; it is not a bug.

OK; closing the bug report.
